I'm not 100% certain, but I believe that the "MatchProduct" section should be "USB-PS/2 Trackball" for your setup.

And I agree with Towo. You don't really need the xorg.conf file.

One more thing. This file seems to get replaced at times when doing a dist-upgrade, so if your trackball stops working after an upgrade you might need to add this code again.

Thanks....I put that config w/ "USB-PS/2 Trackball" into a new 50-marblemouse.conf in /usr/share/X11/xorg.conf.d and it works now.
Gumper: you might want to put it in a separate file...you're modifying a file that's part of the Xorg distribution probably.

Thanks for the xorg.conf removal tip too...my desktop comes up at a higher resolution now
